Hello,

Were you in the process of replacing a drive? If so you may continue with that operation.

Take a look at: Replacing disks in SC Series via the Dell Storage Manager Client

If you were not in the process of replacing this drive then; Have you tried close and relaunch Storage Manager?

Did any of the reporting change?

Verify you on the latest Dell Storage Manager:

20.1.20.48

Have you tried reseating the drive?

Set to Maintenance mode

Remove drive Wait for about 10-15 seconds

Reinsert drive

After reseating the drive and verifying its status, exit maintenance mode to resume normal operations.

If the drive status remains "down" after reseating, it might be necessary to proceed with the replacement.

Dear @DELL-Charles R 

We have did the procedure you mentioned and we tried to replace the disk by a new one.

but the new one won't be recognized by the array

here below the message after the last step of replacing the disk from "dell storage manager client"

We have a repeat the replace procedure many times but always the new drive won't be recognized and won't become UP.

is the new drive also failed ? what to do .. thanks :))

Hello,

Does drive show green led like your first image, or any led ?

Have you verified it is in the correct screw holes of the drive carrier?

Hello :)

Thanks for your quick answer :))

yes the drive show green led  (when i right click on the disk and choose "indicator on" the leds start blinking, just to verify that the slot is responding to Dell storage manager client)

yes it is in the correct screw holes

i think that even the new disk is faulty

Thanks

you should to check whether user allocation block is zero. If it reached to zero, then you can replace the disk.
